Tonight on Grey's Anatomy, Bailey (Chandra Wilson) tries to prep the team with a mandatory sensitivity training before they admit a 700-pound patient with compounded medical issues - the case proves to be challenging in every sense of the word, and Cristina (Sandra Oh) wants to know if they can tell jokes if it's really funny.

Elsewhere on "How Insensitive," Derek (Patrick Dempsey) comes face to face with a former patient's husband in a wrongful death deposition. Finally, Cristina spends time with a heart patient's daughter, which opens up some old wounds for her.

Promos after the jump:
